Hello Monroe

All beginning will be difficult and won't become easier later... ;-)
Ground is nothing special. It means only one common signal rail. An
electrical voltage signal always requires two rails. You may call the
one rail "signal" and the other "ground" (but you don't have to).

Have a look at
http://fa.utfs.org/diy/rc.jpg
There is technically do difference between those two cicuits, only the
kind of graphical depiction is different.
Complex circuit diagrams become much more readable, if you don't line
out the complete ground and powersupply rails. For simple circuits like
the rc-filter it might be superflouos.
